An MTA bus struck and killed a 69-year-old man on Staten Island early Friday morning before leaving the scene, police and transit officials said.

The victim was identified as Pat Varriale, the electronic media services division director for the American Federation of Musicians of US and Canada, an instrumental musicians union.

“He has been phenomenal in how he has worked to improve the lives of musicians throughout the US and Canada," union president Ray Hair said. “There are hundreds of thousands of musicians who don’t know Pat but Pat’s work enabled them to receive the money they deserved for the work they did in electronic media."

Varriale was on his way to work, Hair said.

The bus driver was identified and taken into custody where he told police he didn't realize he hit Varriale, according to police. The bus was traveling eastbound on Forest Hill Road and made a left turn on Platinum Avenue near Latourette Par, striking Varriale as he crossed the street, investigators said.

Around 4:30 a.m., police responded to the intersection and found Varriale lying in the street with severe trauma. EMS pronounced him dead at the scene.

The driver was removed from duty as the MTA and NYPD investigate, MTA sources said.
